WASHING- MACHINE.

SPECIFICATION forming part of Letters Patent No. 467,241, dated January 19, 1892.

Application filed June 4,1891. Serial No. 395,163. (No model.)

To aZZ whom it may concern:

Be it known that we, JOHN SCHROEDER and HENRY T. HAHN, citizens of the United States, and residents of Davenport, Scott county, State of Iowa, have invented a new and useful Improvement in WVashing-Machines, of which the following is a specification.

The invention relates to washing-machines in which a cylindrical tub is used and in which the clothes to be washed are placed within the tub, such clothes being stirred therein by means of a vertical rotating stirrershaft provided with stirrers entering such tub; and our invention consists in providing mechanism for rotating such stirrer-shaft alternately in opposite directions, the mechanism consisting of a novel combination of parts and also details of construction, which will be hereinafter described, and pointed out in the claim.

In the accompanying drawings, Figure 1 represents an end view of such mechanism such tub only being shown. Fig. 2 represents a side view of the same, onlyasectional part of the cover being shown, together with a common form of stirrer used in this class of washing-machines. Fig. 3 is a view in vertical' section on the line m w of Fig. 2, the upright and stirrer being removed. Fig. 4 is a side View of the follower-wheels, enlarged. Fig. 5 is a horizontal sectional view of another form or modification of such followerwheel, and Figs. 6 and 7 are views of another modification of the flanged wheel and follower-wheel.

Similar letters and figures of reference designate similar parts throughout the several views.

We have not illustrated a full view of a washing-tub, as its construction is well known, and our invention only pertains to mechanism for rotating the stirrer-shaft, which is supported by the cover of the tub, which cover and upper part of the tub are illustrated.

A represents the upper portion of a cylindrical or barrel wash-tub; B, its cover. 0 is a vertical stirrer shaft supported in said cover, and D a stirrer attached to such shaft and which stirrer is located on the under side of said cover. The stirrer-shaft projects the drawings,) through which the upper end of the stirrer shaft passes. Two upright posts 11 and 12 are secured to the upper surface of the cover, each provided with bearings to support the horizontal shaft 13. From the foot of the upright post 12 is attached another upright post 14, also provided with a bearing and in line with another bearing 10 in the upright post 12, through which bearings is supported the horizontal drivingshaft 16. Upon either side of the pinion E and supported upon the horizontal shaft 13 are two reverse bevel gear-wheels 17 and 18, the reverse inner faces of the hubs of each being provided with oblique-faced cogs 19, and between such hubs on said shaft is located a longitudinal sliding sleeve 20, the opposite ends of which are provided with similar oblique-faced cogs 21, arranged to become engaged alternately with said cogs 19. Wtrthrn the perforation of such sleeve is a longitudinal tongue 22, which enters the longitudinal groove 23 in the shaft 13, by which means the sleeve maybe moved longitudinally upon said shaft, and is also caused to rotate with the shaft. In the exterior surface of said sleeve is a circumferential groove 24. Located upon the shaft 13 between the post 12 and the bevel gear-wheel 18 is a wheel 25, the rim of which is provided with a flange 26, which flange passes nearly one half around the rim on one side of the rim and around nearly the other half of the rim on the opposite side of such rim, such flange being connected from side to side by the continuation of such flange crossing the face of the rim at an angle, as at 27 27. bines with it an internal spur-wheel, which we designate 28, which engages a pinion 29, secured on the inner end of the drive-shaft 16. The lever 30 is pivoted to'th'e frame 10 by the pivot 31, an end of which lever terminates in the semicircular forks 32, and near the end of each fork is a pivot or guide 33,

The wheel 25 also comprises or com- IOO each of which enters the groove 24 in the sleeve. The opposite end of the lever is pivoted to the horizontal bar Si by a pivot 35 and which horizontal bar passes through a bearing in the post 36, secured to said cover. The end of the bar 34 carries a follower-wheel 37, the rim of which is formed into a semicircular groove for the accommodation of the flange 20. In order that such follower-wheel may follow the flange as it crosses the rim of the wheel, as at 27, we support the axles of such wheel in the ends of a U-shaped frame 38, which frame is provided with a cylindricallyshaped shank 39 and which shank passes through a perforation in the horizontal bar 34, being secured therein by a pin 40, as is illustrated in Fig. 4:. It will be observed that the wheel when so mounted will swivel or turn so as to follow the flange. In order to limit the swivel movement of the wheel, we attach to the frame an L-shaped piece 41, which, by contact with the bar 3i, limits such movements.

A modification of the follower-Wheel is shown in Fig. 5, in which the perforation through the wheel for the accommodation of the axis is contracted in the center and enlarged at the ends and the end of the bar 34 terminating in an axis 42, which passes through such perforation in the wheel, such axis being provided with shoulders 43 for re taining. the wheel on such axis, such arrange ment permittinga limited swiveling movement to the wheel. Ye prefer, however, to use the follower-wheel and mounting shown in Fig. 4 or Figs. 6 and 7, although for greater simplicity in illustration we have shown in Figs. 1, 2, and 3 the wheel described in the detailed view in Fig. 5.

For the purpose of driving the machine we attach at the end of the drive-shaft 16 a handcrank 44.

\Ve have illustrated in Fig. 6 a modification of the flange on the wheel 25. In said view 45 illustrates two flanges upon said wheel, the ends of which are curved, as at 46 and 4:7. The follower-wheel $8 is secured at the end of the bar 34, so that said wheel will rotate against the sides of flanges and pass between the curved parts i6 and 47.

It will be seen by this modification that the follower-wheel will rotate against one side of one flange and the opposite side of the other flange, and in changing the bar 34 will be moved as hereinbefore described.

In operation, when the shaft 16 is rotated, its pinion, by means of engagement with the internal spur-wheel, rotates the wheel 25 and its flange causes the followerwheel to be drawn or moved alternately from one side to the other of the rim of such wheel,imparting like movement to the bar 3t, and which bar swings the lever 30 upon its pivot, and by means of the guides of the semicircular forks entering the groove in the exterior of the sleeve such sleeveis moved alternately an d longitudinally upon the shaft 13, so that its bevel-faced cogs engage alternately with the like cogs upon the hubs of the beveled gearwheels 17 and 18, thus alternately placing each of such beveled geanwheels in engagement with the pinion E, causing its stirrershaft to rotate or partially rotate alternately in opposite directions. We are aware that mechanism has heretofore been described for producing a like movement to such stirrershaft, and we do not broadly claim any mechanism for such purpose, but limit ourselves to our novel combination of parts and details of construction, and

What we claim as new, and desire to secure by Letters Patent, is-

The combination, with a cylindrical washtub, its cover B, stirrer-shaft- O, stirrer D, pinion E, frame 10, the horizontal supported shaft 13, the internal spur-wheel, the drive-shaft, hand-crank,and pinion,and the reverse loose gear-wheels, of the longitudinal sliding sleeve provided with oblique-faced cogs, the hubs on the reverse loose gear-wheels provided with oblique-faced cogs, the lever operating said sleeve, the flange on the rim of the wheel, the follower-wheel, and the supported bar connecting said follower-wheel and said lever, substantially as described.
